Stressed, Sad, Worried

I am currently on leave (since March) due to burnout/depression, and insomnia. I am medicated, and I was so hopeful that I was finally getting better because I can now get out of bed, regularly have breakfast, and open my curtains in the morning. Last week was the first time I felt good in a really long time. I fixed up some things around the house that were weighing on my mind, bought and assembled a nightstand, saw some friends on Friday. It’s still hard to take care of myself unless I have a “reason”, so I literally haven’t showered since Friday. And before then it was probably Monday. I noticed that I have been feeling more and more sad since Saturday and idky. Stayed in bed since then (except to make breakfast, use the bathroom, and open my curtains). I have my first call with a social worker tomorrow and I am really anxious about it. Idk what’s going to happen, idk what to talk about. I didn’t get the chance to bring it up to my therapist last time so idk how to handle this call. I am even feeling more and more anxious while writing this out. Feeling overwhelmed since I have to make supper (for me and my mom).
My therapist says my mom is taking advantage of me (I took her in 4 years ago because prior to that she was homeless for a decade and always refused my help). However, my therapist also made me realize that she’s a hoarder and not 100% mentally there. She hid a garbage bag from me because I was finally motivated to put some of her rotting food in it - literal black goo from being in the fridge for a year - and it spent 3 weeks outside of the fridge in the “hiding spot” until I threw it out). I hope the social worker will help me figure out how to handle this, but idek if we will have the time to talk about everything going on in my situation. Also some financial stressors, work worries, family drama, loneliness (the only ones who talk to me every day are my ex and my mom). Idk what to do and idk what’s wrong with me or why I am feeling like this now. So sad. There’s also more to it, my doctor thinks I might have add, ocd, anxiety, and/or a mood disorder. Last week I told my therapist that I think I might be bipolar (since I have been handling depression on my own on and off since I was really young, and maybe the times I think I’m “normal” are actually the times when I am manic). I’ve also been thinking that maybe I am autistic because of a lot of things + I recently learned that my entire circle of childhood friends are autistic, adhd, or both. Idk what I want my future to look like, I am 10 years past the time I thought I would be gone from this world. Not sure what “flair/category/tag” this post is.
Thank you to whoever reads this.

TLDR: Sad all of a sudden. Handling a lot, taking care of mom. Not sure what mental illnesses I have. Spiraling a little. Also, I think I may be a bit of a hoarder too.
